I forgot to update this thread – I gave
@cgp 's driver a shot with System 6 and the Mac actually booted with this set of HyperCharger drivers!
For some reason, the 2.0 version never seemed to work - System 6 would freeze as soon as it tried to load the driver, but this version works fine.
These appear to be v1.0, and they're not archived anywhere from what I have found. I am so greatful that you took the time to make an image of this,
@cgp !
As far as performance goes, these preform well, but the ExSys drivers that
@Phipli found seem to work better. The only difference being the "Math" score in Speedometer.
HyperCharger: 1.19 (if I remember correctly) vs. ExSys: 14.12
Part of me thinks that ExSys is fudging the results, but I'm not exactly sure.
I can confirm that my HyperCharger does indeed have the FPU.
